• Figure: a combination of geometric objects
  • dots
  • lines
  • areas
• Geometric objects have attributes
  • location
  • color
  • size
  • shape
  • transparency
• Data visualization: mapping categorical/numeric variables to geometric objects and their attributes

• Several skills in big data visualization
• The grammar of ggplot2
• Manipulate aesthetics and plot appearance
• Create publication-ready plots
